Injuries of the sterno-clavicular joint in backpackers

Anterior sterno-clavicular dislocation, or fracture dislocation, as a result of carrying a backpack has not previously been described. We describe two cases, and reflect on the factors that may have led to the injuries, noting that the current PLCE (personal load carrying equipment) may also increase the risk of this condition. The condition is one that carries a grading of U8 (unfit for service), and is one that Medical Officers should be aware of, as it has serious implications for a continuing military career.
